摘要
大肠超声显像液灌注（ＵＢＣＥ）腹部与直肠腔内超声检查结直肠良恶性肿瘤与普查共５２１例，经手术、纤维肠镜活检病理诊断及气钡双重造影与钡灌肠证实，超声对中晚期癌肿的发现率１００％，与病理符合９５．４％，定位准确性９６％；早期肠癌仅２．９％。结直肠息肉＜１．０ｃｍ检出率７４％，１．１～２ｃｍ９６％。频率５ＭＨｚ检出最小息肉０．６ｃｍ×０．４ｃｍ，肠癌０．８ｃｍ×１．４ｃｍ。按癌肿浸润肠壁程度超声分期与病理符合率７５．２％。详述了结直肠癌，息肉，良性肿瘤，肠壁间病变的超声图像与鉴别方法。大肠病变超声普查发现器质性病变４．９％；占高危人群的９．６％与病理符合８１．６％，其中２例大肠癌；并发现血吸虫病大肠的超声表现。对沿海农渔村及血吸虫流行区普查，证实ＵＢＣＥ超声检查不受条件限制，可广泛用于基层，是早期诊断大肠肿瘤简便、有效的过筛方法，有实际应用价值。
Five hundred and twenty one cases were examined by abdominal US during UBCE and endorectal US. The detective rate of moderate and advance stage cancer was 100%. The coincidence rate of US compared with surgery and pathology was 95. 4%. The accurate rate of localization by US was 96%. The smallest bowel cancer detected with 5MHz transducer was 1. 4×0. 8cm. Ultrasonic mass suervey of large bowel diseases showed: organic diseases accounted for 9. 6% of high risk persons.The coincidence rate of US diagnosis compared with Pathological diagnosis was 81. 6%, Bowel cancers were diagnosed in two of them. Ultrasonic survey during UBCE can be performed in basic units. It is a safe, simple and effective screening for early detection of colorectal cancer.
